You know, I'm pretty sure that's NOT a valid MAC address. I'm guessing the LAN chip on your board is dead. You may want to RMA it if you can, or just add a separate LAN card.

Most likely a defective onboard LAN. Foxconn = poor quality, could be a reason why Foxconn is discontinueing motherboard sales under their own name. Try a cheap LAN card to see if the onboard is defective.

Your mac address certainly seems incorrect. In this case, resetting the BIOS might help.

Does the PC attempt to boot from the LAN if you enable it?
